Assessing the impact of Canadian primary care research and researchers: Citation analysis.

Objective: To describe the citation impact and characteristics of Canadian primary care researchers and research publications.

Design: Citation analysis.

Setting: Canada.

Participants: A total of 266 established Canadian primary care researchers.

Main Outcome Measures: The 50 most cited primary care researchers in Canada were identified by analyzing data from the Scopus database. Various parameters, including the number of publications and citations, research themes, Scopus index, content analysis, journal impact factors, and field-weighted citation impact for their publications, were assessed. Information about the characteristics of these researchers was collected using the Google search engine.

Results: On average, the 50 most cited primary care researchers produced 51.1 first-author publications (range 13 to 249) and were cited 1864.32 times (range 796 to 9081) over 29 years. Twenty-seven publications were cited more than 500 times. More than half of the researchers were men (60%). Most were clinician scientists (86%) with a primary academic appointment in family medicine (86%) and were affiliated with 5 universities (74%). Career duration was moderately associated with the number of first-author publications (0.35; =.013). Most research focused on family practice, while some addressed health and health care issues (eg, continuing professional education, pharmaceutical policy).

Conclusion: Canada is home to a cadre of primary care researchers who are highly cited in the medical literature, suggesting that their work is of high quality and relevance. Building on this foundation, further investments in primary care research could accelerate needed improvements in Canadian primary care policy and practice.
